There are 3 spots in the picture where the paint is bubbling up on the wall. The layer of paint that is seperating seems quite thick (roughtly 2mm). Does anyone know what could be happening here and how to fix it?

    Hi Saurabh, I moved from a rental home 2 years ago the spare bedroom wall next to the bathroom did the same exact thing. There was no central a/c and southeast Texas is sooo humid! I think it may be moisture in the drywall under the paint.

    The surface paint could be atop wallpaper ... or there may be an incompatibility between the types of the original and the paint you see. Matte over gloss, etc. From the appearance of the texture, I'd guess the latter. Looks like a complete redo might be in order. :-/

    It looks definitely like moisture damage.

    The surface paint could be a Latex paint over an Oil-based paint that wasn't primed first?

    Definitely water/moisture damage.

    Since it is in the corners, that is where the dry wall is taped and mudded. It is the tape that is coming away from the wall not the paint. It can be due to humitity or too much paint applied when painting the room. I had that problem too and I just slit the tape caulked and used dridex where needed and painted over it. Has lasted for years with no problems. Oh it can also be caused by movement, such as a foundation shifting.

    It looks almost like the paper of the drywall is coming up. I'd slit it with a razor blade and see if there is water damage. I'd mud it back down and touch up the paint.

    I had this problem on an outside wall. I put an air diverter on the floor vent below it. The cold air then blew into the room instead of up the wall, causing condensation. The bubble went away.

    It is more than likely moisture damage, it looks as though the wallboard/Gibrock/Giboard/Drywall/Plasterboard, whatever you call it over there? has absorbed some moisture from somewhere and it doesn't need to be an exterior wall as it could be from a roof leak, before you make any repair you are going to have to find out where the moisture is coming from and repair that first, or it is going to be an ongoing issue, to fix the bubble/wrinkle carefully with a very sharp tool split the corner and put some type of adhesive in behind it and massage the wrinkle back towards the corner, it is so much easier to hide the repair in the corner, it will also help to put a hot steamy cloth over the wrinkles it might take 3 or 4? it softens the substrate and makes it easier to work with, your best friend for the repair will be a tube of Dap type paintable White Gap filler it will also act as a glue as well, there are many to choose from, what is on the other side of the damaged corner?

      Well that is unusual John, it now makes me wonder if it is either ground movement or expansion & contraction of the building during temperature variations, it's been very hot over there this summer are you being hammered by excessive heat? if there is no moisture involved that is where would look next, and that is very hard to fix, have a look at ceiling joints, door/window frame movement as it will show up there too. Good luck!!!!

    we had that happen to us. we bought a house, not a new one and a couple of years down the road, we wanted to change the stark white walls that it had when we bought it. Turns out it was wall paper that had been painted over. So we sighed and got after removing the wall paper in several rooms. Turns out wall paper can only hold so much paint. Hope that is not your problem
